Q1
What is the primary function of arteries?
A Transport blood to the heart
B Transport blood away from the heart
C Microcirculation within tissue
D Gas exchange in the lungs
CORRECT ANSWER B. Transport blood away from the heart
CLINICAL RATIONALE
Arteries carry oxygenated blood (except pulmonary artery) away from the heart under high pressure.
They have thick, muscular walls to withstand pressure and maintain flow.
, Q2
What is the primary function of veins?
A Transport blood away from the heart
B Transport blood to the heart
C Gas exchange in the lungs
D Microcirculation within tissue
CORRECT ANSWER B. Transport blood to the heart
CLINICAL RATIONALE
Veins carry deoxygenated blood (except pulmonary veins) back to the heart under low pressure. They
have thinner walls, larger lumens, and valves to prevent backflow, especially in the lower extremities.
Q3
What is the function of capillaries?
A Transport blood away from the heart
B Transport blood to the heart
C Microcirculation within tissue (exchange of gases, nutrients, wastes)
D Gas exchange in the lungs only
CORRECT ANSWER C. Microcirculation within tissue (exchange of gases, nutrients, wastes)
CLINICAL RATIONALE
Capillaries are single-cell-thick vessels forming networks (capillary beds) where diffusion of oxygen,
carbon dioxide, nutrients, and wastes occurs between blood and interstitial fluid.
